METHODOLOGY OF TEACHING FRICTION FORCES IN NATURE AND TECHNOLOGY IN HIGHER EDUCATIONAL INSTITUTIONS

Abstract

the article consists and is necessary to develop and study the positive and negative influence of friction forces on the development of the Republic from the economic side as a result of performing a certain amount of work and energy expenditure to overcome their useful and harmful side, friction forces. Friction forces are of great importance in nature. If friction did not exist, the nails one trips over would fall off, all rubber compounds would fail, our clothes would not stand on the place of buttons. We would have attached furniture to the floor to keep it from sliding around. It would be impossible to explain the motion of a diesel locomotive, an automobile, and other vehicles without saying that a person walking without friction would feel free and without regard to friction. The car and train are propelled by the wheel on the surface of the road, that is, by the frictional forces between the rails in trains. The frictional forces between the pulleys and the bar allow motion to be transferred from one wheel to another. Friction is used in metalworking (in pressing, cutting, twisting), in various friction devices (for the transmission of motion and power, as well as in the operation of actuators). From the above examples, it is clear that in the absence of dry friction, most actions can not be performed. What is friction to know why?, types, it is important to know the causes of friction.
